BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to an electronic imaging device, and more particularly, to an electronic imaging device for displaying a normal planar image and/or a stereoscopic image according to an input signal.
2. Description of the Related Art
In general, humans perceive a stereoscopic effect based on a physiological factor and an experiential factor, and a three-dimensional image displaying technology expresses a stereoscopic effect of an object by using a binocular parallax, which is a primary factor for allowing humans to recognize a stereoscopic effect at a short distance.
Electronic imaging devices generally display a stereoscopic image by spatially separating an image into a left image and a right image using optical elements. Representative examples of the optical elements used to display a stereoscopic image include a lenticular lens array and a parallax barrier.
Recently, an electronic imaging device capable of displaying both of a normal planar (or two-dimensional) image and a stereoscopic image was developed and has become commercially available.
However, image quality of an electronic imaging device that can selectively display a planar image and a stereoscopic image may deteriorate due to the operating characteristics of optical elements. Particularly, the image quality is deteriorated when a planar image changes to a stereoscopic image and vice versa. That is, when a planar image changes to a stereoscopic image, all of the optical elements simultaneously switch to a driving mode to display a stereoscopic image. Then, if a planar image is displayed on a certain area of a display screen (that may be predetermined), the planar image is displayed through the optical elements in the driving mode to display the stereoscopic image. Similarly, when a stereoscopic image changes to a planar image, all of the optical elements switch to a transmission area. Here, if a stereoscopic image is displayed on a certain area of a display screen (that may be predetermined), the stereoscopic image is displayed through the transmission area.
As such, the image quality is deteriorated when a planar image changes to a stereoscopic image or vice versa because the operating state of the optical elements is not matched with a certain area of a display screen.
The above information disclosed in this Background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

As shown in
The display unit 100 includes a plurality of scan lines S1 to Sn for transferring selection signals, a plurality of data lines D1 to Dm insulated from and crossing the plurality of scan lines S1 to Sn and for transferring data signals, and a plurality of pixels 105 formed at crossings of the scan lines S1 to Sn and the data lines D1 to Dm. In the present exemplary embodiment, each of the pixels 105 includes a red subpixel for displaying red (R) color, a green subpixel for displaying green (G) color, and a blue subpixel for displaying blue (B) color. In the present exemplary embodiment, the plurality of pixels 105 in the display unit 100 include pixels corresponding to a left-eye image (hereinafter, also referred to as ‘left-eye pixels’) and pixels corresponding to a right-eye image (hereinafter, also referred to as ‘right-eye pixels’). The left-eye pixels and the right-eye pixels are alternately and/or repeatedly arranged. In more detail, the left-eye pixels and the right-eye pixels are alternately and/or repeatedly arranged in parallel, thereby forming a stripe pattern and/or a zigzag pattern. The arrangement of the left-eye pixels and the right-eye pixels may be changed according to the first and second barriers 110 and 120. The pixels 105 of the display unit 100 according to one embodiment include one or more organic light emitting elements (or diodes) and one or more pixel circuits for driving the one or more organic light emitting diodes.
Referring to
The pixel circuit is formed at each crossing of one scan line Si among the plurality of scan lines and one data line Dj among the plurality of data lines, and is connected to each scan line and the data line. The driving transistor M1 generates a driving current corresponding to a voltage applied to its gate electrode and its source electrode. The switching transistor M2 is turned on in response to a selection signal transferred from the scan line Si, and when the switching transistor M2 is turned on, the data signal transferred from the data line Dj is transferred to the gate electrode of the driving transistor M1. The capacitive element C1 has first and second ends respectively connected to the gate electrode and the source electrode of the driving transistor M1, and uniformly sustains the voltages of the first and second ends. Then, the driving transistor M1 generates a driving current IOLED corresponding to a difference between the voltage of the data signal transferred to the gate electrode of the driving transistor M1 and a power source voltage VDD applied to the source electrode of the driving transistor M1. The generated driving current IOLED flows to the OLED through a drain electrode of the driving transistor M1. The OLED emits light corresponding to the driving current IOLED.
The scan driver 200 is connected to the scan lines S1 to Sn of the display unit 100 and applies a selection signal formed of a combination of a gate on voltage and a gate off voltage to the scan lines S1 to Sn. The scan driver 200 may apply the selection signals to the plurality of scan lines S1 to Sn to sequentially have a gate on voltage. When the selection signal has the gate on voltage, the switching transistor connected to the scan line is turned on.
The data driver 300 is connected to the data lines D1 to Dm of the display unit 100, and applies a data signal representing a gray level to the data lines D1 to Dm. The data driver 300 converts input image data DR, DG, and DB, which are input from the controller 400 and have gray level information, to a voltage-type or a current-type data signal.
The controller 400 receives an input signal IS, a horizontal synchronization signal Hsync, and a vertical synchronization signal Vsync, generates a scan control signal CONT1, a data control signal CONT2, an image data signal DR, DG, or DB, and a barrier driver control signal CONT3, and respectively transfers the generated signals to the data driver 300, the scan driver 200, the data driver 300, and the barrier driver 500. The scan control signal CONT1 includes a scan start signal for instructing to start scanning and a first clock signal. The data control signal CONT2 includes a horizontal synchronization start signal for instructing transferring of input image data for pixels of one row and a second clock signal. The controller 400 may transfer the input image data DR, DG, and DB through three channels by color when input image data for one row is transferred to the data driver 300, or may sequentially transfer the input image data DR, DG, and DB through one channel.
The input signal IS input to the controller 400 may be one of normal planar (or two-dimensional (2D)) image data, three-dimensional (3D) graphic data including 3D spatial coordinates and surface information of an object to be three-dimensionally displayed on a planar surface, and stereoscopic image data including image data of each view point. The input signal IS may include planar image data and stereoscopic data when the display unit 100 displays a planar image and a stereoscopic image together. The controller 400 according to the present exemplary embodiment decides (or selects) one of a 2D driving mode or a 3D driving mode according to an input signal for driving. In more detail, the 2D driving mode is a driving mode that displays a planar image by driving the first and second barriers to transmit an image to be displayed on the display unit as it is, so as to not induce binocular parallax. The 3D driving mode is a driving mode that displays a stereoscopic image by driving one of the first barrier or the second barrier according to a scan direction of the display unit to form a transmission area and a non-transmission area repeatedly (and/or alternately), thereby inducing binocular parallax.
The barrier driver 500 operates as the 2D driving mode or the 3D driving mode according to a barrier driver control signal CONT3. The barrier driver 500 according to the present exemplary embodiment drives the first barrier 110 or the second barrier 120 by being synchronized with an image displayed on the display unit 100. In more detail, the controller 400 generates a scan signal according to a horizontal synchronization signal. The display unit 100 displays images of each row according to scan signals sequentially transferred from the plurality of scan lines S1 to Sn. Here, one of the first barrier 110 or the second barrier 120 is selected according to the scan direction of the display unit 100, and operates when a stereoscopic image is displayed. The barrier driver 500 generates and transfers a plurality of first barrier driving control signals CB_1[1] to CB_1 [p] to control the first barrier 110, and generates and transfers a plurality of second barrier driving control signals CB_2[1] to CB_2[q] to control the second barrier 120. The electronic imaging device according to an embodiment of the present invention will be described in more detail with reference to
The first barrier 110 includes a plurality of first sub-barriers 110_1 to 110—p. Each one of the plurality of first sub-barriers 110_1 to 110—p is formed corresponding to at least one of the scan lines. Each first sub-barrier 110_1 to 110—p includes a plurality of first electrodes E1 and a first connection electrode C1. Each first sub-barrier 110_1 to 110—p is turned on in response to a voltage level of the first barrier driving control signal when the first barrier driving control signal is applied. Each of the plurality of first sub barriers 110_1 to 110—p receives a corresponding first barrier driving control signal CB_1[1] and CB_1[p] from the barrier driver 500. Each first sub-barrier 110—i is turned on in response to an on-level of a first barrier driving control signal CB_1[i], where i is a natural number (e.g., positive integer) from 1 to p, and forms a non-transmission area.

That is, the first barrier driving control signal CB_1[1] becomes a high level and the sub-barrier 110_1 is turned on by being synchronized with the timing T11 where the selection signal select[1] drops from a high level to a low level.

The switching transistor transfers a data signal to a driving transistor when the selection signal is at a low level. That is, the sub-barrier 110_1 is turned on by being synchronized with the timing of displaying an image of one pixel circuit row.

Further, the first barrier driving control signal CB_1 [2] becomes a high level and the sub-barrier 110_2 is turned on by being synchronized with the timing T12 where a selection signal select[5] drops from a high level to a low level. Then, the display unit 100 displays a stereoscopic image on an area corresponding to the scan lines S5 to S8. In an identical (or substantially identical) way, the first barrier driving control signal CB_1[3] becomes a high level, and the sub-barrier 110_3 is turned on by being synchronized with the timing T13 where a selection signal select[9] drops from a high level to a low level. Then, the display unit 100 displays a stereoscopic image on an area A corresponding to the scan lines S9 to S12.
In the same (or substantially the same) way, a stereoscopic image of a current frame is displayed on the entire display unit 100.

Further, the second barrier driving control signal CB_2[2] becomes a high level and the sub-barrier 120_2 is turned on by being synchronized with the timing T22 where a selection signal select[4] drops from a high level to a low level.
Then, a stereoscopic image is displayed on an area of the display unit 100 corresponding to the scan lines S4 to S6 arranged next to (or to follow) the plurality of scan lines S1 to S3. As described above, the second barrier driving control signal CB_2[4] accordingly becomes a high level, and the sub-barrier 120_4 is turned on by being synchronized with the timing T23 where a selection signal select[10] drops from a high level to a low level. Then, a stereoscopic image is displayed on an area B of the display unit 100.
In view of the foregoing, the electronic imaging device according to the present exemplary embodiment has been described to include both of the first barrier 110 and the second barrier 120. However, the present invention is not limited thereto, and an electronic imaging device may selectively include only one of the first barrier 110 or the second barrier 120.
With reference to
Since the electronic imaging device only includes the first barrier 110 as shown in
The display unit 100 and the first barrier 110 are disposed in a first direction shown in the drawing, and operate in a manner substantially the same as shown and described with reference to
Then, when the display unit 100 and the first barrier 110 rotate 90° and a stereoscopic image is displayed, the first barrier 110 turns on all the sub-barriers 110_1 to 110—p regardless of the timing of transferring the plurality of selection signals sequentially along the plurality of scan lines. Thereby, a stereoscopic image is displayed.
An electronic imaging device having a second barrier 120 operates in a manner substantially the same as shown and described with reference to
The electronic imaging devices according to the first and second exemplary embodiments provide sharper image quality using a barrier operated by being synchronized with a selection signal when a planar image changes to a stereoscopic image.
Hereinafter, an electronic imaging device according to another exemplary embodiment of the present invention will be described.
As shown in
The barrier 130 includes a common transparent electrode (common ITO) 132, a liquid crystal layer 133 and glass substrates 134.

In more detail, the barrier driver 500″ applies barrier driving voltages CB_3[1] to CB_3[k] to the transparent electrode cells 131 by being synchronized with the timing of displaying an image at a plurality of pixels along a scan direction of the display unit 100.
Hereinafter, the operation of the barrier driver 500″ will be described with reference to
As shown in
When a selection signal is applied to a scan line (a) and a data signal is applied to each pixel of the display unit 100 so as to display an image, a barrier driving voltage is transferred to transparent electrode cells 131 of odd numbered barrier cells BPX among the transparent electrode cells 131 of the plurality of barrier cells BPX forming the first sub-barrier 130_11 of the barrier 130. In the same (or substantially the same) way, when a selection signal is applied to a scan line (b) and a data signal is applied to each pixel of the display unit 100 so as to display an image, a barrier driving voltage is applied to transparent electrode cells 131 of odd numbered barrier cells BPX among the transparent electrode cells 131 of the plurality of barrier cells BPX forming the first sub-barrier 130_12 of the barrier 130. When a selection signal is applied to the scan line (c) and a data signal is applied to each pixel of the display unit 100 so as to display an image, a barrier driving voltage is transferred to transparent electrode cells 131 of odd numbered barrier cells BPX among the transparent electrode cells 131 of the plurality of barrier cells BPX forming the first sub-barrier 130_13 of the barrier 130. When a barrier driving voltage is transferred to the transparent electrode cells 131, the barrier cells BPX become non-transmission areas. In an identical (or substantially identical) way, the plurality of barrier cells BPX forming the barrier 130 operate by being synchronized with a stereoscopic image displayed on the display unit 100 in the first scan direction.

As a result, the second sub-barrier 130_21 becomes a non-transmission area. Likewise, a barrier driving voltage is applied to transparent electrode cells 131 of a plurality of barrier cells BPX forming the second sub-barrier 130_22 by being synchronized with the timing of applying a selection signal to the scan line (e). As a result, the second sub-barrier 130_22 becomes a non-transmission area.
A barrier driving voltage is applied to transparent electrode cells 131 of a plurality of barrier cells BPX forming the second sub-barrier 130_23 by being synchronized with the timing of applying a selection signal to the scan line (f). As a result, the second sub-barrier 130_23 becomes a non-transmission area. In the same way, the plurality of barrier cells BPX forming the barrier 130 operate by being synchronized with a stereoscopic image displayed along the second scan direction. In this manner, odd numbered second sub-barriers among the plurality of the second sub-barriers 130_21 to 130_2y are driven by being synchronized with the timing of transferring a selection signal to a scan line along the second scan direction, and the odd numbered second sub-barriers become non-transmission areas.
